WILLIAM L. MOSER, OF WINSTON-SALEM, NORTH CAROLINA.

VENDING MACHINE.

Application filed February 3, 1922. Serial No. 533,915.

To all whom it may can earn:

Be it known that I, WVILLIAM L. Mosna, a citizen of the United States, residing at VVinston-Salem, in the county of Forsyth and State'of North Carolina, have invented a new and useful Vending Machine, of which the following is a specification.

This invention relates to a vending machine and is designed primarily as an improvement upon the structure disclosed in Patent No. 1,366,129 issued to me on J anuary 18, 1921. 7

It is an object of the invention to provide a simple and compact mechanism whereby when coins or a coin of the proper denomination are inserted into the machine the mechanism will be unlocked and the operator can actuate the mechanism so as to cause the dispensing portion thereof to deliver the article or articles paid for.

Another object is to provide a coin controlled mechanism which is securely locked against movement in any direction unless first released by the insertion of a-proper coin.

Another object is to provide means for preventing actuation of the mechanism should a washer be inserted in lieu of a coin.

Another object is to provide yielding means for holding the mechanism properly set to receive a coin prior to the actuation of the machine.

\Vith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the eombin-ation and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment'of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a front elevation of a vending machine having the present improvements combined therewith.

Figure 2 is a section on line 2-2, Figure 1, the coin indicating plate being removed.

Figure 3 is a plan view of the mechanism shown in Figure 2, the casing being removed.

Figure 4 is an end elevation of the mechanism shown in Figures 2 and 3 but illiis- Secured on the shaft 5 so as to rotate' therewith is a block 8 which, in the present instance, 1s provided in one face with two coin receiving slots 9 each of which opens through one end of the block. Projections 10 are provided on the slotted face of the block 8 at the advancing corners thereof when the shaft and block are rotated clockwise. Slots 11 are formed in the block 8 at right angles to the slots 9 and open into the respective slots 9, each oflthese slots 11 being provided with a pivoted dog 12. A prong 13 extends from each dogand normally projects into theadjacent slot 9 as shown in Figures 2 and 3. j

A standard 14 mounted on the base 15 of the casing 6 provides a bearing for the shaft 5 and secured to this housing is a spring strip 16 the free end of which is offset to provide a locking tongue 17 extending normally into the path of one of the projections 1.0. If the block 8 has two coin slots it is preferred to have a second spring strip 18 mounted on a post 19 and provided at its free end with an offset portion 20 constituting a locking tongue normally projecting into the path of the other projection 10. Each of the spring strips 16 has an intermediate nose 21 extending toward the end of the block 8 and normally situated at a point between the slot 9 and the projection 10 at said end.

Obviouslythe tongues 17 and 20 will operate normally to prevent rotation of the shaft 5 in one direction. For preventing the block from rotating in the opposite direction a stop dog 22 is pivotally mounted on a post 23 and normally projects close to that side of the block remote from the projection 10. This will be apparent by referring to Figure 2. A pin 24 extends from the standard 14 and constitutes the bearing for a spring finger 25 secured to and extending from the shaft This spring finger serves to hold the block 8 normally with the slot 9 directly under and in register with coil receiving slots in the casing 6 and one of which has been illustrated at 26.

The locking tongues 17 and 20 bear against and are guided by a crossstrip 27 mounted on the standard lat and upon a post 28. Pivotallyconnected to this strip are opposed bell cranks 29, One arm of each bell crank extends outwardly beyond the strip 27 while the other arms of the bell cranks project between the tongues 17 and 20. Thus by drawing the outer arms of the bell cranks toward each other, the other arms will press against the tongues 17 and 20 and force them out of the paths of the projections 10, thereby to permit the shaft and the block 8 to be rotated freely in a clockwise direction. It is designed to release the parts in this manner when the table 2 is to be loaded or refilled but it is to be understood that the mechanism cannot be unlocked in this way except by someone who has access to the interior of the casing 6 either by unfastening the casing from the base or by some other convenient means.

When it is desired to release the dispensing mechanism to permit the actuation thereof by the customer, coins of the proper denominations are inserted downwardly through theslots 26 so as to become seated within the slots 9. The coins will be of sufficient weight to thrust aside the prongs 13. After the coins havebeen deposited they will pro'ject laterally from the block 8 and when the shaft 5 is rotated these projecting portions of the coins will come against the noses 21 and shift the lockingv strips 16 and 18 away from the block so as to withdraw the tongues 17 and 20 from the paths of the projections 10. Thus the rotation of the shaft 5 can be continued in a clockwise direction, the spring finger wiping over or snapping past the pin 24 and the block 8 moving downwardly to an inverted position where the coins will gravitate therefrom. Continued clockwise movement will bring the block against the dog 22 which will be lifted out of the path thereof and the block will finally be brought to position as shown in Figure 3 with the dog 22 holding the block against reverse movement and the tongues 17 and 20 preventing further clockwise movement. One rotation of the shaft will be sufficient to rotate the table 2 the dis tance necessary to bring a purchased article to delivery position.

Should a washer'be inserted in one of the slots 9 the prongs 13 would project into the opening therein as shown in Figure 4: with the result that the washer could not slide out of the slot when the block 8 is inverted but will be held suspended and will come against a stop pin which willprevent further rotation of the block. Thus the machine will be kept out of commission until an authorized person removes the washer.

Although the block 8 has been illustrated with two coin receiving slots it is to be un derstood that only one slot need be used if the article to be dispensed can be purchased with a single coin. For example if the price of an article is five cents one slot will beused to receive the nickel. A single slot is also used for receiving a coil of any other denomination although in practice it has been found preferably to use two nickels in lieu of a dime in order to secure the most satisfactory results.

lVhatis claimed is I In a vending machine the combination with anactuating shaft and a table driven by the shaft, of a block rotatable with the shaft and having a coin receiving recess, said block being angular in cross sectional contour, apivoted dog cooperating with the corner'portions' of the block for holding said block against retrograde movement, a spring strip yieldingly mounted adjacent one end ofthe block, a locking tongue extending laterally from the strip, a projection on the block for engagement with the tongue to hold the block against rotation, said strip having a laterally offset intermediate portion for engagement by a coin seated in the recess, thereby to shiftthe tongue out-of the path of projection to release the block, and means engaging the tongue for shifting the strip and tongue to release the block inclependently of the use of a coin, a projection adjacent the shaft, and a spring linger rotatable with theshaft for intermittent wiping engagement with the projection, said finger and projection normally cooperating to hold the recess in the block in coin receiving posit-ion.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.

WILLIAM L. 'MOSER.
